Objective:
To investigate the mechanisms of TWS119 induced CCR5 expression in hunman γδT cells.Methods:
After treatment with various concentrations of TWS119 for 48h, the expression of CCR5 in γδT cells were detected by flow cytometry. The p-STAT3 and GAPDH expression were examined by Western blot analysis.Results:
TWS119 could upregulate the expression of CCR5 in dose dependent manner. Western blot analysis revealed that TWS119 inhibit phosphorylation of STAT3,but had no significant impact on GAPDH. In addition, pretreatment of γδT cells with 0. 5 μmol/L STAT3 specific phosphorylation inhibitor Stattic could upregulate the expression of CCR5 and enhance the TWS119 induced CCR5 expression.Conclusion:
TWS119 could upregulate CCR5 expression of γδT cells by inhibiting STAT3 phosphorylation in vitro.
